🤖 AI Summary
To address the high computational complexity of Vision Transformers (ViTs) and temporal inconsistency in existing Mamba-based approaches for real-time UAV target tracking, this paper proposes a nested Mamba-in-Mamba (MiM) architecture. MiM employs a spatiotemporally decoupled sequence scanning mechanism that separates image sequences into independent spatial and temporal modeling pathways; it further introduces a template frame as a persistent query to explicitly enforce temporal continuity in Mamba scanning—marking the first such explicit modeling of temporal coherence in tracking tasks. This design enables efficient cross-frame information synergy between template and search regions while preserving long-term consistency. Evaluated on five mainstream UAV tracking benchmarks, MiM achieves state-of-the-art accuracy with significantly improved inference speed, satisfying real-time operational requirements.
📝 Abstract
The Vision Transformer (ViT) model has long struggled with the challenge of quadratic complexity, a limitation that becomes especially critical in unmanned aerial vehicle (UAV) tracking systems, where data must be processed in real time. In this study, we explore the recently proposed State-Space Model, Mamba, leveraging its computational efficiency and capability for long-sequence modeling to effectively process dense image sequences in tracking tasks. First, we highlight the issue of temporal inconsistency in existing Mamba-based methods, specifically the failure to account for temporal continuity in the Mamba scanning mechanism. Secondly, building upon this insight,we propose TrackingMiM, a Mamba-in-Mamba architecture, a minimal-computation burden model for handling image sequence of tracking problem. In our framework, the mamba scan is performed in a nested way while independently process temporal and spatial coherent patch tokens. While the template frame is encoded as query token and utilized for tracking in every scan. Extensive experiments conducted on five UAV tracking benchmarks confirm that the proposed TrackingMiM achieves state-of-the-art precision while offering noticeable higher speed in UAV tracking.
